The Scottish Premier League has opened an investigation into allegations of pro-IRA chanting at Celtic Park.

The SPL's operations officer, Iain Blair, confirmed that, in his role as match commander at the Celtic versus Hibernian league game at Parkhead on 29 October, the former referee and senior policeman Eddie Smith complained to a match delegate about songs sung during the goalless draw.

"Eddie mentioned to our delegate that there was pro-IRA chanting from one specific section of the stadium," Blair said. "It was included in the report and is now subject to an ongoing investigation."

It has been reported that two arrests were made during the Hibs match.

Blair also told the Daily Record: "I am currently gathering information about what happened during the match when the arrests were made. We need to find out more about when it happened and what exactly went on. We also have to establish that Celtic, as I am sure they will have, co-operated fully with the police in the aftermath of this event."
